  • This adaptation is most often limited to a position adjustment length of the seat, relative to the vehicle floor, lengthwise of it, possibly adjusting the seat in the direction of height, and to an adjustment of the steering wheel position in one and / or the other of these two directions, in addition to the configuration of the seat itself.
  • the purpose of the present invention is to provide a device overcoming these disadvantages, it being understood that even if this device has was designed more specifically for controlling an organ activation of a vehicle brake assist system automotive, it can find its application in any foot control, by a seated user, a system actuator any.
  • a device according to the invention offers any adjustment stroke, in the length of the vehicle, without varying the level and the orientation of the pedal relative to this floor, it being understood that this advantage is found whatever the application envisaged.
  • the race of adjustment is in fact limited only by the space available for the device, and can reach several tens of centimeters, which allows meet all needs.
  • the seventh axis merges with the fourth or fifth axis, but we can also predict that either offset from these two axes, angularly and / or distance from the second or third axis respectively, this which allows to introduce a bevel gear effect and / or an effect multiplier or multiplier between the tilting movement of the pedal and the movement transmitted to the actuating member.
  • first and second levers are double and have a first branch respective articulated on the one hand on the supporting structure, respectively around the second or third axis, and on the other hand on the rod, respectively around the fourth or fifth axis, and a second respective branch secured to the first branch respectively at level of the second or third axis and having a free end defining an eighth or ninth axis respectively, the eighth and ninth axis being parallel to the first axis, mutually spaced of a distance identical to that which separates the second and third axes and the distance between each other the eighth and second axes being identical to the distance separating each other ninth and third axes, only on the free ends of the second branches is articulated, around the eighth and ninth axes, a connecting rod coupling between the two levers, defining a parallelogram deformable with the second branches of the latter and with the supporting structure, and that the connecting rod is articulated around the seventh axis on the free end of the second branch of one of the first and second levers.

  • the system controlled by means of a device is a brake assist system for a vehicle, advantageously provides that the support also carries, so articulated around tenth and eleventh axes parallel to the first axis or confused with it, an accelerator pedal and, if necessary, a clutch pedal.
  • accelerator pedal and any pedal clutch are traditionally connected to the bodies they control by funicular transmission, usually by cable BOWDEN, which does not cause the same difficulties, in the event of adjustment of the pedals lengthwise of the vehicle, that the connection by articulated linkage that is used to transmit the movement of the brake pedal to the actuator of the assistance system braking.
  • FIGS. 1 to 5 We will first refer to the example of implementation of the invention illustrated in FIGS. 1 to 5, where 1 has designated a foot pedal braking, standing above the floor 2 of the vehicle, in front of the seat 3 of the driver if we refer to a specific direction 4 forward vehicle, so that it can be requested by a foot 5 of the driver in the direction of tilting forward to control a sliding, towards the rear, of a rod 6 constituting the member actuation of a servo-brake 7 disposed behind the pedal 1.
  • a foot pedal braking standing above the floor 2 of the vehicle, in front of the seat 3 of the driver if we refer to a specific direction 4 forward vehicle, so that it can be requested by a foot 5 of the driver in the direction of tilting forward to control a sliding, towards the rear, of a rod 6 constituting the member actuation of a servo-brake 7 disposed behind the pedal 1.

  • this sleeve 90 is drilled right through unreferenced bore of axis 91 perpendicular to axis 89 and fitted with a pad not shown in which it receives, with possibility of relative sliding along axis 91 without other possibility of displacement relative, a straight rod 92 disposed under the wall 11, at all points analogous to rod 54 and guided, like this one, so as to allow a tilting of the pedal 85 forwards, around the axis 83, from a limit orientation illustrated in solid lines in FIG.
  • the rod 92 has a rear free end 93 and a front free end 94 articulated about a respective axis 95, 96 parallel to the axis 89 located in the same plane not referenced as these axes 95 and 96, on a free lower end 97, 98 of a respective lever 99, 100 otherwise articulated, by an upper end 101, 102, around a respective axis 103, 104, parallel to axis 83 with which axes 103 and 104 are coplanar as well as axes 41 and 42 are with axis 9, under a respective yoke 105, 106 fixedly attached under the wall 11, respectively behind the notch 18 and in front of it, i.e.
  • the distance between axes 95 and 96 is identical to the distance between axes 103 and 104, as well as the distance separating axes 103 and 93 is identical to the distance between axes 104 and 94 as well as to the distance separating the axes 83 and 89, so that the levers 99 and 100 constitute with the rod 92 and the wall 11, or more precisely the plane 113 of the axes 103 and 104 fixed relative to it, a deformable, articulated parallelogram around axes 93, 96, 103, 104, and that pedal 85, suitably oriented during assembly so that a plane passing through axes 89 and 83 either parallel to the planes passing respectively through axes 95 and 103 and by axes 96 and 104, itself forms a deformable parallelogram with the rod 92, the wall
  • lever 99, not shown, or lever 100 revolves around an axis 107 parallel to axis 106 and which can be confused with axis 96, not shown, or offset from this, away from the axis 104 and / or angularly, as illustrated, on a free rear end 108 of a connecting rod straight link 109 extending forward from this end free 108, to a second free end or front end 110 articulated around an axis 111 parallel to the axis 108 in a yoke 112 integral with the rod 6 of the servo-brake 7.
  • the recall of the latter towards its position of absence of stress results in an exit from the rod 6, again, out of the servo-brake 7 and the mounting is such that at each instant, the position of the rod 6 is representative of that of the pedal 86 in orientation around the axis 83 relative to the plate 17 and to the wall 11, and this regardless of the position of the axis 83 from one to the other of the positions front and rear limits obtained by adjusting the position of the plate 17 in the direction 16 relative to the wall 11.
  • the sleeve 90 able to slide along the rod 92, is not opposed to this adjustment of axis position 83.
  • a direct connection could be used between the connecting rod 72 and the rod this, with reference to the example illustrated in FIGS. 1 to 5, in the manner of the example described with reference to Figure 6, just as one could provide an indirect link, similar to that described in reference to FIGS. 1 to 5, in an assembly similar to that of which has been described with reference to Figure 6.
  • the device according to the invention could be the subject adaptations to fields of application other than that of braking control of a motor vehicle without going out to as much within the scope of the invention.
